5.6.2. 2-Point Calibration
The following steps explain how to cali-
brate bin scale with the 2-point calibration
method. The bin has to be empty prior to
the calibration.
A) Calibrating the Empty State
1. From the main menu, select:
» 7. Installation*
» 2. Calibration.
» x. Select the desired bin
» 2. Bin #x Two Pts
» 1. Bin #x Empty
*This menu is only accessible from the installer
mode (see sec. 5.2).
7.2.1 Calib Bin 1
Stability tol: 2000
Min Weight
0kg
Push + for next step
Min Calib? No
2. Set the following parameters:
Stability Tolerance —
The controller can only
calibrate a bin when the weight reading of the
bin is stable enough; otherwise, the control-
ler displays an error message. The stability
tolerance is the stability value the controller
can tolerate to calibrate the scale. By default
it is set to 2000.
The weight reading may be unstable in windy
conditions. We thus suggest to wait for a
mild day to perform the calibration. If this is
not possible, increase the stability value in
steps of 1000 each time the controller gives
an error message.
Minimum Weight —
Ideally, the bin should
be empty prior to calibrating the empty bin
status (Min Weight = 0 kg). However, if a
certain amount of feed is already present in
the bin before the empty state calibration,
specify this feed weight (minimum weight).
Calibrate Minimum State ? —
Select "Yes" to
calibrate the empty status of the bin scale.
The message "Please Wait" is displayed. Wait
until the end of the calibration (this process
may take a few minutes).
If calibration is successful, the message "Please
Wait" disappears and the "- - - - " display
switches back to "No"; if it fails, the controller
displays "ERROR". In case of an error, increase
the stability tolerance value by 1000 then try
calibrating the scale once again.
B) Calibrating the Loaded State
1. Fill up the bin with a precise amount of
feed.
2. From the main menu, select:
» 7. Installation*
» 2. Calibration.
» x. Select the desired bin
» 2. Bin #x Two Pts
» 2. Bin #x Full
*This menu is only accessible from the installer
mode (see sec. 5.2).
7.2.2 Calib Bin 1
Stability tol: 2000
Max Weight 10000 kg
Push + for next step
Max Calib? No
3. Set the following parameters:
Stability Tolerance —
The controller can only
calibrate a bin when the weight reading of the
bin is stable enough; otherwise, the control-
ler displays an error message. The stability
tolerance is the stability value the controller
can tolerate to calibrate the scale. By default
it is set to 2000. The weight reading may be
unstable in windy conditions. We thus sug-
gest to wait for a mild day to perform the
calibration. If this is not possible, increase the
stability value in steps of 1000 each time the
controller gives an error message.

Problem
Cause
Solution
The main controller
does not turn on.
The wiring is incorrect.
a) Turn off the power.
b) Remove all wires from the MODULE
terminals of the main controller.
c) Wait 5 minutes.
d) Apply power to the main controller: if
the controller starts, then there is a wiring
problem.
e) Fix the wiring.
Fuse F1 is blown.
Replace the fuse.
The internal light
of the relay module
does not flash
The wiring between the relay
module and the main controller is
incorrect.
Fix the wiring.
The ID number is incorrect
Make sure the ID number of the relay mod-
ule is set to ID #5
The end of line jumpers
are not positioned correctly
Set the end of line jumpers to YES at both
ends of the communication line. Other end
of line jumpers must be set to NO.
The relay module
is defective.
Replace the defective module.
The weight reading
is too high.
The load bar is distorted.
Replace the load bars
The weight
reading is not
correct
If the bin has been calibrated with
the 1-point calibration mode :
The load bar sensitivity is not set
properly in the controller.
Make sure the sensitivity of load bars
specified in the controller corresponds to
reality. The sensitivity value written on the
load bar's calibration certificate correspond
to the sensitivity value posted in the con-
troller (see sec. 5.6.1).
If the bin has been calibrated with
the 2-point calibration mode :
The sensitivity of load bars may
have changed with time.
Redo the 2-point calibration once a year or
each time the bin gets empty.
The output voltage of the load bar
exceeds 15mV (1V for instance).
Check your wiring.
Replace the load bars.
The Vdiv1 voltage is higher than
the entry voltage (V
in
)
Check your wiring.
Replace the load bars.
The Vdiv1 voltage is higher than
the entry voltage (V
in
)
Check your wiring.
Replace the load bars.
(...) The weight
reading is not
correct
Load bars are not connected
Be sure load bars are connected properly.
A wire has been severed.
Replace the severed wire.
The LCT-3 module is defective
Replace the LCT-3 module.
